We are a mid-sized UK law firm specialising in employment law, contract disputes, and corporate litigation. Our website receives high traffic from prospective clients researching their legal options. The Problem Our paralegal team spends 3-4 hours daily answering the same repetitive questions from website visitors — questions that are already answered in our 40+ internal documents including service guides, fee structures, and process explainers.

What We Need An intelligent chatbot embedded on our website that: - Answers visitor questions from our internal documents only - Never fabricates answers — cites the source document - Silently scores visitor intent in the background - Captures contact details when a visitor is ready to engage - Notifies our team via email and Slack when a high-intent visitor is identified Budget is flexible for the right candidate. Expected timeline 4 to 6 weeks. How to Apply Please include: 1. A similar RAG or document chatbot you have built — use case, tech stack, and outcome 2. A live link or demo video of your work 3. Your recommended tech stack for this project and why 4. Your proposed timeline and price We are looking for someone who has done this before.

We’re building an AI mastering tool centered around SAM Audio (Segment Anything Model for Audio), bringing prompt-driven audio segmentation directly into the mastering workflow. Instead of mastering a stereo file blindly, we use SAM Audio style sound and event segmentation to make mastering context aware. The system isolates vocals, drums, transients, tonal elements, and ambience, then processes them intelligently using Artificial Neural Networks trained on large scale music datasets. If you’re comfortable working at the intersection of Python, Deep Learning, Machine Learning, Data Science, and professional audio engineering, this role is for you. We’re building a next generation AI mastering engine powered by: SAM Audio based segmentation with text, time span, and event guided sound isolation Artificial Neural Network models for mix analysis and mastering decision prediction Transformer based audio embeddings and feature learning Data driven tonal balance modeling using large reference datasets Intelligent loudness optimization with LUFS and True Peak control Neural enhancement modules including denoise, transient shaping, and harmonic excitation Core idea Segmentation and learned embeddings first, object aware mastering decisions second, transparent reconstruction at the end.

Predicting House Prices Using Machine Learning Applied	$50	9 hours ago	Client Rank - Medium Payment method verified Phone number verified 1 open job no reviews Registered: Mar 12, 2026 South Africa 05:09 3
This project focuses on building a simple machine learning model to predict house prices based on key features such as location, size, number of bedrooms, and number of bathrooms. A dataset containing historical housing data will be used to train the model. The process will include data cleaning, exploratory data analysis (EDA), feature selection, and training a regression model such as Linear Regression. The model’s performance will be evaluated using metrics like Mean Absolute Error (MAE) and R² score. The goal of the project is to demonstrate how machine learning can be used to make data-driven predictions and gain insights from real-world datasets.

Data Extraction Specialist for Polymarket Sports Trading Historical Dataset Applied	$60	9 hours ago	Client Rank - Medium Payment method verified Phone number verified $160 total spent 6 hires 49 jobs posted 12% hire rate, 6 open job 4.88 of 5 reviews Registered: Jun 20, 2025 Bangladesh Mymensingh 08:09 3
I need to build a complete dataset of every individual trade ever executed on sports betting markets on Polymarket, a prediction market platform running on the Polygon blockchain. The end goal is a structured file where each row represents a single trade fill, containing the wallet address, the market and event it belongs to, which sport/league it falls under, the outcome being traded, price per share, number of shares, USDC amount, timestamp, transaction hash, and whether that wallet was the maker or taker. Each row should also include the settlement result of that market (which outcome won) so that I can calculate profit and loss on my own. The dataset needs to be granular and complete enough that I can perform any analysis I want on trader behavior, performance, and patterns after delivery — the analysis itself is not part of your scope, only the data extraction and structuring. Polymarket's sports markets run through a specific smart contract called the NegRiskCTFExchange on Polygon. Every trade settlement emits an OrderFilled event on-chain containing both wallet addresses (maker and taker), the token IDs being exchanged, and the amounts. There are approximately 191 million total OrderFilled events across all market categories, and the sports subset is estimated at 76 to 115 million fills across 300,000 to 600,000 individual markets. The primary challenge of this project is extracting that volume of on-chain data cost-effectively and matching it to the correct market metadata. I have already completed a full scrape of Polymarket's Gamma API, producing a 2.8 GB file of all 264,000 events (with tags identifying the sport/league) and a 6.2 GB file of all 1.2 million individual markets (with condition IDs, token IDs, outcomes, and resolution data). These files will be provided to you along with a detailed technical handoff document covering every API endpoint, contract address, data quirk, and known pitfall discovered over several weeks of prior work. What remains is: parsing the existing event data to produce a definitive list of all sports markets and their token IDs, extracting the full on-chain trade history for those markets (likely via eth_getLogs on a Polygon archive node, which is free and feasible in roughly 2,400 API calls on Alchemy's free tier), joining the trade data to market metadata and resolution outcomes, and enriching wallet addresses with Polymarket usernames via their public profile API. The recommended approach is direct RPC queries against a Polygon archive node since bulk export from Dune Analytics is cost-prohibitive at this data volume, though I'm open to alternative methods if you can achieve the same completeness. The final deliverables are three files: a trade-level dataset with every sports fill matched to market metadata and settlement outcomes, a market metadata reference file with every sports market's details and resolution result, and a wallet profile lookup table mapping addresses to Polymarket usernames for active traders. I'm looking for someone with hands-on experience querying blockchain data at scale, specifically using eth_getLogs, decoding EVM event logs, and working with archive nodes on Polygon or similar chains. You should be comfortable handling datasets in the hundreds of millions of rows and have a reliable pipeline for processing and storing that volume. Familiarity with Polymarket, prediction markets, or the Gnosis Conditional Token Framework is a strong plus but not required — the technical handoff document covers the architecture in detail. In your proposal, please describe a project you've completed involving large-scale blockchain data extraction, explain how you'd approach pulling 76 to 115 million event logs from Polygon efficiently, and give me a realistic timeline and cost estimate. I'll share the full technical documentation and pre-scraped data files with serious candidates before work begins.

Indoor Human Navigation Behaviour Modelling Applied	~23 - 196 USD	13 hours ago	Client Rank - not enough data -
I am wrapping up an engineering project on “getting around an indoor space by modelling human navigation behaviour” and I need help finishing the core pieces. The goal is to extract the latest findings from academic journals on how people move through buildings—specifically how they avoid obstacles in office layouts—and turn those insights into a working simulation that can be stress-tested on randomly generated floor plans. Here’s how I see the work flowing: • Literature synthesis: comb through peer-reviewed papers, identify the dominant theories and quantitative parameters that govern obstacle avoidance in offices, and summarise them in a concise technical review. • Behavioural model: translate the selected research into an algorithmic model (agent-based, continuous steering forces, or a hybrid if justified) that captures obstacle avoidance while still allowing for pathfinding on an abstract office graph. • Simulation engine: code a lightweight simulator (Python with Pygame, Unity C#, or another well-documented toolchain) that can import or procedurally generate office maps containing static and dynamic obstacles, drop an agent, and run repeatable experiments. Each run should randomise the layout so the model’s robustness is clear. • Engineering report: compile methodology, model equations, simulation screenshots, performance metrics, and critical discussion into a structured report suitable for an academic or industry audience. Acceptance criteria 1. Literature section cites only academic journals (IEEE, ACM, Elsevier, Springer, etc.) and covers at least 4 primary studies from the last decade. 2. Model code is clean, version-controlled, and accompanied by a README with setup instructions. 3. Simulation must allow a seed value to guarantee reproducibility of the random office layouts. 4. Simple summary report: Explain theory, link findings, model assumptions, simulation results, and improvement suggestions. If you have prior work on human movement, robotics path planning, or agent-based crowd simulations, this will be a perfect match.

The project required urgent development of a WordPress site, initially publishing two main pages with plans to add the rest later.

Senior Product Data Scientist – Experimentation Applied	$30 - $80 / hr	16 hours ago	Client Rank - Medium Payment method verified Phone number verified 8 jobs posted 2 open job no reviews Company size: 10 Registered: Jan 12, 2024 United Kingdom 03:09 3
About the Role We are a financial services technology business at an important inflection point. We have a functioning data science capability – including an intent model already in use and a cohort forecasting tool in development – but we now need to accelerate our path toward a robust experimentation and decision intelligence capability. We are looking for a senior individual contributor who has helped build this kind of capability before: someone who understands how behavioural data, experimentation, modelling and product decisions fit together in a production environment. This role is not purely about building models. It is about helping the company establish a disciplined experimentation and decision analytics capability: defining hypotheses, designing experiments, ensuring reproducible model development, and helping the team turn behavioural data into measurable product outcomes. You will be the most senior data voice in the business during a critical stabilisation and build phase, working directly with the Founder and alongside a senior analytics infrastructure contractor who is spec-ing the data platform and guiding broader infrastructure work. What You Will Work On - Mentorship and Team Development - Provide day‑to‑day technical mentorship to a mid‑level data scientist working on intent modelling and early experimentation work - Guide a analytics engineer / data analyst on statistical methodology, particularly for a cohort forecasting tool we are developing - Review code, provide structured feedback, and raise the statistical rigour of the team's outputs - Help the team establish good habits around experimentation, documentation, reproducibility and model lifecycle discipline Experimentation Framework - Design and begin implementing a practical experimentation framework suited to a long‑lifecycle financial product context - Define how hypotheses are formulated, how borrowers are exposed to experiments, and how outcomes are measured - Establish standards for experiment design, randomisation, statistical power and result interpretation - Help implement the core experimentation loop: hypothesis → exposure → intervention → outcome measurement - Collaborate with the analytics infrastructure contractor and backend engineers to ensure experiments can be executed reliably in the product Model Lifecycle and Monitoring - Assess the current state of model lifecycle management across existing models and forecasting tools - Introduce reproducible model development practices including experiment tracking, model versioning and training reproducibility - Help design lightweight but robust monitoring for model performance and data drift appropriate to the company’s scale - Advise on model deployment approaches (MLFlow, SageMaker or equivalent) while prioritising simplicity and reliability Feature Design and Behavioural Modelling - Guide the design of behavioural signals and feature sets derived from product interaction data - Ensure the analytics and dbt layer supports both experimentation and modelling - Contribute to feature engineering and model evaluation for intent modelling and related behavioural prediction problems - Help the team think clearly about the progression from descriptive analytics → experimentation → predictive models → decision optimisation Who We Are Looking For - Strong Python: production‑quality code, not just notebooks - Experience deploying and managing models in production environments (AWS preferred; SageMaker, MLFlow or equivalent tools acceptable) - Strong applied understanding of supervised learning models used in behavioural or product contexts - Experience working with dbt or similar modern analytics engineering practices - Experience designing or implementing experimentation frameworks in product environments - Strong statistical thinking: experimentation, hypothesis testing and causal reasoning - Genuine mentorship ability: you get satisfaction from making others better - Financial services domain experience or strong interest in regulated data environments What Good Looks Like at 90 Days - The team focused on data products is materially stronger: better statistical practice, cleaner code and clearer experiment design - A practical experimentation framework is defined and implementation has begun - Exposure tracking and experiment measurement are in place for early product experiments - Model training and evaluation workflows are reproducible and monitored - The cohort forecasting work has sound statistical foundations - A clear picture exists of how behavioural data, experimentation and modelling should evolve in the platform Client's questions: What techniques would you use to clean a data set?

We are a Meta ads performance marketing agency building an AI intelligence system that connects 5 years of agency data: ad performance, client communications, creative briefs, financial records, and document history. We have a detailed architecture plan and an in-house developer building the pipelines. We need an experienced analytics engineer to review the architecture, identify problems before we build on them, and advise during the build. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ THE CORE CHALLENGE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Our data refers to the same entities (clients, ads, people) inconsistently across sources: - The same client appears as "Brand X Pty Ltd" in our accounting software, "Brand X AU" in Meta Ads, "BRANDX" in our spreadsheets, and only by first name in emails. - The same ad appears as "CLIENT-089 \| Product Name \| Static \| Variant \| 1350" in our tracking sheet and "Client Product Variant V2 Static" in Meta Ads Manager. - Client contacts are referenced by first name only in email threads. We need this solved before any data gets entered — not cleaned up after. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT WE NEED YOU TO DO ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1. Architecture review (Week 1) Review our 13-table BigQuery schema and pipeline plan. Identify structural problems: entity resolution gaps, join key risks, schema decisions that will be painful to change at scale. Deliver: written review with specific recommendations. 2. Entity resolution design (Week 1-2) Design the strategy for resolving the same client, ad, and person across different source systems. Build: client aliases reference table, contact directory structure, ad name canonicalisation rules. Deliver: documented matching rules + BigQuery lookup tables. 3. Claude API optimisation (Week 2) Advise on BigQuery schema decisions that affect LLM query performance: partitioning, clustering, authorised views for LLM-safe data surfaces. Deliver: optimisation recommendations + authorised view specifications. 4. Pipeline review during build (Weeks 2-4) Review each pipeline before it runs on real data. Available for questions from our developer (a few hours/week). Flag issues before they become data quality problems. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ THE DATA SOURCES — WHAT WE ARE CONNECTING ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ This is a multi-source architecture with 14+ databases spanning: PAID ADVERTISING PERFORMANCE - Meta / Facebook Ads (API via Windsor): ad-level daily performance — spend, ROAS, CPA, impressions, frequency, hook rate, hold rate - Google Ads (API via Windsor): same structure, cross-channel attribution AD CREATIVE — STATICS AND VIDEO - Creative intelligence spreadsheet (Google Sheets sync): every ad ever made, tagged with creative taxonomy (hook type, format, funnel stage, emotion) - Static images: Claude Vision analysis (text overlay %, faces, UGC aesthetic, emotional register, visual complexity) - Video ads: Whisper transcription + FFmpeg frame extraction + Claude Vision on key frames. Hook line, narrative structure, timestamp-level key moments. - Asset storage: Google Cloud Storage, linked to creative intelligence records RECORDED KNOWLEDGE — LOOMS AND ZOOM - Loom recordings: strategy sessions, training videos, client walkthroughs, screen-share recordings of account management in action - Zoom recordings: team meetings, client calls, training sessions - Both: Whisper transcription + scene-change frame extraction + Claude API summary and training value scoring. Highest complexity — videos have multiple linked layers (ad unit, asset, transcript, frames, training moments). COMMUNICATIONS - Gmail (5 team accounts, 5 years): Gmail API backfill + Push Notifications for real-time. Claude API enrichment: client classification, sentiment, topic category, summary. LLM-safe authorised view filters noise. - Slack: historical workspace export + Events API real-time - WhatsApp: manual export (no API available for personal accounts) - Future: Google Chat if used DOCUMENTS AND IP - Google Drive (all accounts): every document ever created — strategy docs, SOPs, QBRs, proposals, reports, briefs, meeting notes, brand guidelines, onboarding documents, research, contracts - Google Slides: exported per-slide as PNG images, Claude Vision reads each slide - Intellectual property and proprietary methodology: separate BigQuery dataset with stricter access controls — NOT exposed to the same LLM surfaces as operational data PROJECT MANAGEMENT AND BRIEFS - Basecamp (API): 5 years of project history, todos, messages, documents - Creative brief database: Drive/Notion briefs → Claude extraction → structured brief records linked to the ads they produced - Motion (creative project management app): API for production time per task, enabling true cost-per-ad calculation FINANCIAL - Xero (API): full invoice and payment history, retainer revenue by client, contractor costs, profitability by client SALES PIPELINE - 5 years of sales conversations reconstructed from email archive and founder memory: every prospect, outcome, reason won/lost CUSTOMER DATA - Shopify (direct Admin API per client store): full order history, customer LTV, UTM attribution linking ads to acquired customers - Klaviyo (API): email marketing performance, list health, revenue per send The entity resolution challenge spans ALL of these. The same client, person, and ad appears differently in almost every source. This is the core problem we need you to solve before data entry begins. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ TECH STACK ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ BigQuery (primary data warehouse) Google Cloud Platform (Cloud Functions, Cloud Run, Pub/Sub, Secret Manager) Python / Node.js (pipeline code — Claude API generates most of it) Anthropic Claude API (enrichment and intelligence layer) Google Cloud Storage (creative asset storage) ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT WE PROVIDE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ - Full architecture plan and 13-table schema (you review, not design from zero) - Access to our in-house developer for questions - Detailed documentation of all data sources and their inconsistencies - Fast responses (same business day, AEST timezone) ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT WE NEED FROM YOU ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ - Production BigQuery experience (not just familiar — have built and run BigQuery pipelines that other people depend on) - Experience with entity resolution or data matching across messy real-world sources (not clean, well-structured datasets) - Understand the tradeoffs in schema design: partitioning, clustering, normalisation vs denormalisation for LLM workloads - Can explain WHY you make architecture decisions, not just implement them - Available for at least 15 hours in Week 1 for the architecture review ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ DURATION AND RATE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Duration: 3-5 weeks intensive, then ~5 hours/week available for questions Estimated hours: 40-60 hours total Rate: negotiable based on experience and location Start: as soon as possible — we have a sprint beginning shortly Budget: not specified 16 hours ago Client's recent history (50+ works) Jobs in progress (7) Virtual Assistant for Coda Knowledge Base Setup — Immediate Start Feb 2026 - Present 14 hrs @ $5.52/hr Billed: $78.25 AgencyAnalytics Expert – Build Automated Weekly Performance Deck (Start TODAY) Feb 2026 - Present 27 hrs @ $9.04/hr Billed: $240.99 Meta Ads Uploader & Campaign Operator Nov 2025 - Present 87 hrs @ $15.86/hr Billed: $1,382.89 Meta Ads Uploader & Campaign Operator Sep 2025 - Present 298 hrs @ $12.63/hr Billed: $3,764.79 Urgent – Social Media Content & Growth Assistant Aug 2025 - Present 63 hrs @ $17.62/hr Billed: $1,115.64 mail Address Research Specialist for URL and LinkedIn Profile Lists Sep 2024 - Present FIXED $566.00 Meta Ads Copywriter Sep 2024 - Present View more (2) data mining project No feedback given Sep 2025 FIXED $64.00 Data Mining No feedback given Aug 2025 FIXED $32.70 additional data mining No feedback given Jun 2025 FIXED $1,308.27 Seeking an Experienced On-Page SEO Specialist for Immediate Work No feedback given Oct 2024 FIXED $503.00 Meta Ads Video Editor No feedback given Sep 2024 161 hrs @ $26.31/hr Billed: $4,245.05 Video Editor for Scroll-Stopping Meta Ads (Facebook & Instagram) To freelancer: 5 To client: 5 Nov 2025 - Feb 2026 21 hrs @ $21.48/hr Billed: $450.99 Instagram Content Creator for Performance Marketing Agency (15-20 Posts) To freelancer: 5 To client: 5 Oct 2024 - Feb 2026 FIXED $50.00 Video Editor for Scroll-Stopping Meta Ads (Facebook & Instagram) To freelancer: 5 To client: 4.4 Aug 2025 - Feb 2026 FIXED $340.00 Graphic Designer - Static ads (Canva Expert, Remote) To freelancer: 5 To client: 5 Nice to work with you Courtney Jul 2025 - Feb 2026 FIXED $120.00 Cold Email Lead Generation Specialist To freelancer: 5 Oct 2024 - Feb 2026 FIXED $1,200.00 Spreadsheet optimisation To freelancer: 5 To client: 5 Everything went smoothly, nice experience working with Matt Feb 2025 - Feb 2026 5 hrs @ $37.75/hr Billed: $188.74 Brand Designer for Agency Brand Refresh To freelancer: 5 Jan 2025 - Feb 2026 FIXED $4,500.00 Meta Ads Copywriter for Creative Strategy (Static & Video) To freelancer: 5 To client: 5 Feb 2025 - Feb 2026 FIXED $200.00 Digital Tracking Specialist for Ongoing Projects To freelancer: 5 To client: 5 May 2025 - Feb 2026 50 hrs @ $21.10/hr Billed: $1,051.49 Video Editor Wanted for Epic Japan Trip Highlight Reel To freelancer: 5 To client: 5 Matt was clear in what he wanted, yet still flexible with creative experimentation.

Fabric Defect AI Research Article Applied	$15 - $25 / hr	18 hours ago	Client Rank - not enough data -
I am preparing a full-length research article on automated fabric defect detection in industrial environments, driven by convolutional or hybrid neural networks coded in Python with TensorFlow or PyTorch. The end goal is a manuscript ready for submission to a Q2 Scopus-indexed journal, followed through peer-review until final acceptance. What I need from you • Curate or locate a high-quality, publicly shareable dataset (or assemble one from open sources) that covers common textile defects in varied lighting and weave patterns. • Design, train, and tune an appropriate neural-network architecture; document every experiment so the methodology section is fully reproducible. • Produce clear performance analyses—confusion matrices, precision-recall curves, ablation studies, and industrial-scale inference benchmarks. • Draft all sections of the paper (abstract to conclusions), conforming to the target journal’s template and reference style. • Manage the entire submission workflow, including cover letter, responses to reviewers, and revision rounds. Acceptance criteria 1. Model achieves at least state-of-the-art results on the chosen dataset or convincingly surpasses published baselines. 2. Manuscript meets every formatting guideline of the selected Scopus journal and passes plagiarism and language checks. 3. All code, trained weights, and experiment logs are delivered in a clean Git repository with a brief README for replication. If you are fluent in Python-based deep learning, comfortable with academic writing, and have previous papers indexed by Scopus, I would love to collaborate. Include a link to one relevant publication and a brief outline of how you propose to structure the study.
